Metroid Prime 2 gets reviewed tonight at IGN

[BreakABone]

I think the problem with putting a grand story into Metroid is really the type of game it is. She is a solo bounty hunter, usually on an alien planet where most of the people want her dead or vice versa. there are hardly any, if any at all NPCs for her to interact with. I mean they could try and force people into the story, but I will think it would take away from the whole isolation, You vs Them type deal.

With that said, I would suspect that Samus would have more interactions with the Luminoths, maybe some of the Federation Troopers and even Dark Samus in this game, but it's all my assumption.
